- Describe how polygenic inheritance may result in a continuum of phenotypes.With regard to pedigree analysis, make a list of observations thatdistinguish recessive, dominant, and X-linked patterns of inheritance.Pedigree analysis is a fundamental tool for investigating whether or not a trait is following a Mendelian pattern of inheritance. It can also be used to help identify individuals within a family who may be at risk for the trait. Adam and Sarah, a young couple of Eastern European Jewish ancestry, went to a genetic counselor because they were planning a family and wanted to know what their chances were for having a child with a genetic condition. The genetic counselor took a detailed family history from both of them and discovered several traits in their respective families. Sarahs maternal family history is suggestive of an autosomal dominant pattern of cancer predisposition to breast and ovarian cancer because of the young ages at which her mother and grandmother were diagnosed with their cancers. If a mutant allele that predisposed to breast and ovarian cancer was inherited in Sarahs family, she, her sister, and any of her own future children could be at risk for inheriting this mutation. The counselor told her that genetic testing is available that may help determine if this mutant allele is present in her family members. Adams paternal family history has a very strong pattern of early onset heart disease. An autosomal dominant condition known as familial hypercholesterolemia may be responsible for the large number of deaths from heart disease. As with hereditary breast and ovarian cancer, genetic testing is available to see if Adam carries the mutant allele. Testing will give the couple more information about the chances that their children could inherit this mutation. Adam had a first cousin who died from Tay-Sachs disease (TSD), a fatal autosomal recessive condition most commonly found in people of Eastern European Jewish descent. Because TSD is a recessively inherited disorder, both of his cousins parents must have been heterozygous carriers of the mutant allele. If that is the case, Adams father could be a carrier as well. If Adams father carries the mutant TSD allele, it is possible that Adam inherited this mutation. Because Sarah is also of Eastern European Jewish ancestry, she could also be a carrier of the gene, even though no one in her family has been affected with TSD. If Adam and Sarah are both carriers, each of their children would have a 25% chance of being afflicted with TSD. A simple blood test performed on both Sarah and Adam could determine whether they are carriers of this mutation. Would you decide to have a child if the test results said that you carry the mutation for breast and ovarian cancer? The heart disease mutation? The TSD mutation? The heart disease and the mutant alleles?

Are these good odds?Discuss the concept of multifactorial inheritance, and include two examples.
- What is polygenic inheritance? Discuss the issues that make polygenicinheritance difficult to study.Describe how traits can exhibit incomplete penetrance and vary in their expressivity.Describe the concept of the extended phenotype. Can you think of a trait that you consider to be your own that could perhaps be due to the genetics of another organism you’ve interacted with in your life?
- Provide a proof that a different phenotype can be produced from the same genotype. What are the possible causes for this different expression? How can the different gene interactions be differentiated from each other and from the Mendelian inheritance?Discuss the differences among sex-influenced, sex-limited, andsex-linked inheritance. Give examples.Briefly discuss Mendelian Inheritance with that of crossing-over.
